患者男性,33岁。临床诊断:病毒性心肌炎,心律失常。心电图为不连续记录的Ⅱ导联(附图),P_1、P_2直立,P-R间期>0.12s,为窦性P波,频率77次/min(P-P0.78s)。P_1’及以后一连串P’波形态较小,呈负正双向,正向波大于负向波,出现于舒张晚期,P’-R间期>0.12s,基本频率94次/min(p’-P’0.64s),尚规则,其P’-R间期
Male patient, 33 years old. Clinical diagnosis: viral myocarditis, arrhythmia. The electrocardiogram was discontinuous record of Ⅱ lead (with photos), P_1, P_2 upright, P-R interval> 0.12s, sinus P wave, the frequency of 77 beats / min (P-P 0.78s). P_1 ’and the subsequent series of P’ waveforms were smaller, negative and positive in both directions, and the positive wave was larger than the negative wave, appearing in late diastole. The P’-R interval was> 0.12s and the basic frequency was 94 beats / min (p’- P’0.64s), still rules, its P’-R interval
